Marine Corps Air Station El Toro (ICAO: KNZJ, FAA LID: NZJ) was a United States Marine Corps Air Station located near Irvine, California. Before it was decommissioned in 1999, it was the 4,682 acres (19 km2) home of Marine Corps aviation on the West Coast. Designated as a Master Jet Station, its four runways (two of 8,000 feet (2,400 m) and two of 10,000 feet (3,000 m)) could handle the largest aircraft in the U.S. military inventory. While it was active, all U.S. Presidents in the post-World War II era landed in Air Force One at this airfield. The El Toro "Flying Bull" patch was designed by Walt Disney Studios in 1944. It survived virtually unchanged until the close of the Air Station.
